Passed the essentials today with a score of 893/900, almost a perfect score. I plan to take the 220-602 (Technician) on the 17th, but pretty much I consider my self certified, since rumor has it Technician is easier.

As far as study materials, I read the Sybex Complete book and took as many practice test as I could get my hands on. I also have had a lot of experience, so that surely contributed.
Things to know:
- ntbooddy.sys
- DHCP, APIPA
- MSDS
- Upgrade paths (Win2k - XP, etc)
- Customer Service
- Chkdsk, Defrag
- System Restore, ASR, ERD
- Printers (Nothing in depth)
This is also my introduction as well since I could not find a section for that lol.
